The fully automated Vectra Polaris Quantitative Pathology Imaging System is a new class of tissue imager which provides oncologists, immunologists, and pathologists unparalleled speed, performance, and versatility for extracting

proteomic and morphometric information from intact FFPE tissue sections or TMAs. Vectra Polaris goes beyond basic functions, like whole slide, brightfield, and fluorescence imaging. It integrates the power of multispectral imaging in a simplified elegant workflow.

With multispectral imaging, you can capture the multiple interactions occurring between cells without the issue of autofluorescence and crosstalk. That means you can have confidence in accurately quantifying the interactions that are really occurring in the biology and not worry about false positives. Coupled with the proven power of inForm software analysis, this multiplexing capability enables identification and quantification of multiple biomarkers and reveals spatial context within a digital workflow to assist researchers with faster, more informative studies.

PerkinElmer has developed Vectra Polaris to be a unique standalone platform, purpose-built to provide all the essential tools needed in advancing the fields of immuno-oncology and digital pathology now and in the future.

The First All-in-One Solution for Immuno-Oncology

The Vectra Polaris Automated Quantitative Pathology Imaging System is a cutting edge tool for revealing the cell-to-cell biology driving tumor progression, immune interactions, and response to therapeutic interventions such as with checkpoint inhibitors. By combining tissue imaging with multiplexing, the Vectra Polaris system can capture this biology with a workflow that supports the volume and high-throughput demands of clinical research studies.

Example Applications

• Phenotyping immune cells for cancer immunology research

• Transduction signaling pathway activity (pAKT, pERK, pS6, p13K/mTOR, MAPK, or EGFR)

• Apoptosis and/or proliferation assays

• Necrosis and fibrosis using conventional stains

• Cell cycle characterization

• DNA damage determination

• Inflammation

• Lymph node metastasis

• Autoimmune diseases

Discover New Tissue Biomarkers in Context

For cancer immunology researchers who are seeking to understand the role of immune cells within solid tumors and their microenvironment, the Vectra Polaris analyzes, quantifies and phenotypes immune cells in situ, in FFPE tissue sections and TMAs. The Vectra Polaris system's multispectral technology enables the removal of autofluorescence, improving the signal-to-noise ratio substantially. This allows for a more sensitive and accurate analysis of samples, and enables true cell-to-cell interaction to be revealed, coupled with multicolor IHC reagents designed for best signal isolation. Researchers can see up to seven markers in a tissue section (Figure 1), revealing cell types, spatial context, quantification of multiple biomarkers and cell-to-cell interactions (Figure 2). Vectra Polaris seamlessly integrates this data into a digital pathology workflow and can provide whole section context, in BF and FL modes.

Meet the Demands of High-Throughput Studies

Vectra Polaris is a fully automated, high-throughput system which uses the most advanced optics, mechanical design, and imaging sensors to deliver high performance whole-slide scanning (Figure 4), combined with focused multispectral analysis, to accelerate your research and maximize your lab’s resources. It can be programmed to suit your unique study requirements. Choose from a flexible array of scanning options, including whole slide imaging and pattern-recognition guided multispectral (MSI) region selection and acquisition. The human interface is designed for the demands and dynamics of translational labs, with a workflow that efficiently integrates pathologist oversight (Figure 5).

For FL, tissue was stained with the Opal 7-color fIHC kit. Lower panels show zoomed in views of the whole slide scans. Typical whole slide imaging speeds @ 20X: FL, eight slides/hr (4 colors); BF, 15 slides/hr.

Figure 5. Vectra Polaris features an intuitive yet flexible workflow that allows the pathologist to view a whole-slide contextual scan and select regions of interest for multispectral acquisition: shown here in the Pathologist-Selection workflow (top). Another option is to enable selection and acquisition of multispectral regions by Vectra Polaris with help from inForm: shown here in the Automated-Selection workflow (bottom). inForm can be trained by the pathologist to recognize regions of interest and the algorithm stored for Vectra Polaris' use in selecting regions that meet the desired criteria. In all scenarios, the pathologist can review and ultimately approve the results of the quantitative analysis. The benefit to automated selection is consistency and much greater throughput while retaining the option for review at each step by the pathologist.

inForm Quantifies Biomarkers in Tissue Sections

Vectra Polaris utilizes inForm software analysis to combine the power of multiplexed biomarker imaging and quantitative analysis all within a familiar digital workflow to accelerate immuno-oncology research.

inForm allows users to accurately and reliably separate multiple biomarker signals from one another and from autofluorescence in multiplexed assays (seven colors). Extract per-cell multiparameter data from one or more cell compartments in order to generate tissue-based analysis that retains the architectural context of the intact tissue.

inForm Tissue Finder automates the detection and segmentation of specific tissue types using patented user-trainable algorithms that can recognize morphological patterns. It includes per-cell phenotyping functionality to differentiate marked cell types (e.g. T-cells, macrophages) within a segmented area (e.g. tumor versus stroma) (Figure 6).
